New changelog entries:
* multiarch_dev.patch: Replace definition of GMP_NUMB_BITS calculated by
configure with the same calculation to be done at compile time (only
used if this package would be rebuilt with --enable-mini-gmp). Thus
declare nettle-dev Multi-Arch: same (Closes: #856160).
* Upgrade to Debhelper compat level 9.
* Drop old style -dbg package and switch to automatically created
-dbgsym packages. Since the old package was built with Debhelper level
8 there are actually no file conflicts.
* Declare nettle-bin Multi-Arch: foreign.
* Bump Standards-Version to 4.1.0.

New changelog entries:
* multiarch_dev.patch (new): Remove compiler version info causing
nettle-dev for different architectures to be incompatible with each
other from nettle-stdint.h (Closes: #783699).
* Rearrange debian/copyright to comply with the machine-readable format
specification.

New changelog entries:
* Tag a symbol that only exists on 64-bit architecture.
* native_64bit_test_needs_limits_h.patch: Include limits.h in
camellia-absorb.c; needed by the HAVE_NATIVE_64_BIT macro on at least
s390x.
* Add manpage for nettle-pbkdf2.
